Description

Technical Field

[0001] This utility model relates to the technical field of RTO combustion-assisted combustion equipment, specifically, to an RTO combustion-assisted combustion equipment. Background Technology

[0002] Industrial production processes generate large amounts of waste gas containing organic pollutants. Direct release into the atmosphere can cause severe environmental pollution and harm human health. Currently, commonly used waste gas treatment equipment includes direct-fired incinerators and catalytic combustion equipment. However, traditional direct-fired incinerators, when burning fuels (such as diesel and heavy oil), easily produce harmful substances like dust, smoke, and sulfides. This not only fails to thoroughly purify the waste gas but also causes secondary pollution. Furthermore, some equipment has low thermal efficiency, failing to effectively recover the heat generated during combustion, leading to significant energy waste and high operating costs. During operation, combustible gases can easily remain in the combustion chamber, and the lack of an effective purging and cleaning mechanism poses an explosion risk. With increasingly stringent environmental regulations and rising demands from enterprises for energy-saving, safe, and efficient production, there is an urgent need for waste gas treatment equipment that is environmentally friendly, has high energy utilization, and is highly safe. RTO (Regenerative Thermal Oxidation) combustion aid equipment has emerged as a result. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an RTO combustion aid device. The device uses natural gas as the combustion fuel. Natural gas is a clean energy source and does not produce harmful substances such as dust, smoke and sulfides during combustion. Natural gas itself has a high calorific value and complete combustion, and its thermal efficiency is much higher than that of traditional fuels such as diesel and heavy oil. The heat generated by combustion can be utilized to the greatest extent.

[0004] An RTO (Regenerative Thermal Oxidizer) combustion aid device includes a base on which a regenerative combustion furnace is fixedly mounted. A combustion torch is located on the upper part of one side of the regenerative combustion furnace. A combustion unit is located on one side of the regenerative combustion furnace. The air inlet of the combustion unit is fixedly connected to one end of a natural gas pipeline, and the other end of the natural gas pipeline is fixedly connected to a natural gas supply pipe. The air inlet of the combustion unit is fixedly connected to the air outlet of a combustion aid fan through an air supply pipe. The combustion unit is connected to the combustion torch through a pipe.

[0005] Furthermore, the gas outlets at the upper and lower ends of one end of the regenerative combustion furnace are respectively connected to the chimney via gas outlet pipes.

[0006] Furthermore, the upper and lower parts of the regenerative combustion furnace are respectively fixedly equipped with maintenance platforms, the upper maintenance platform is connected to the second ladder, and the lower maintenance platform is connected to the second ladder.

[0007] Furthermore, a purge fan is also provided on one side of the regenerative combustion furnace. The outlet of the purge fan is connected to the inlet of the purge pipe, and the purge pipe is fixedly connected to the lower part of the other side of the regenerative combustion furnace.

[0008] Furthermore, inspection ports are provided at both ends of the upper part of one side of the regenerative combustion furnace.

[0009] Furthermore, an air inlet is provided at the lower part of the other end of the regenerative combustion furnace.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are: The equipment uses natural gas as fuel. Natural gas is a clean energy source that does not produce harmful substances such as dust, smoke, and sulfides during combustion. It only emits carbon dioxide and water, thus avoiding secondary pollution at the source. At the same time, after the exhaust gas enters the regenerative combustion furnace through the air inlet, it fully exchanges heat with the high-temperature gas produced by combustion. After being heated to the oxidation temperature, it undergoes an oxidation reaction, which can completely decompose the organic pollutants in the exhaust gas into harmless carbon dioxide and water, resulting in high purification efficiency. On the one hand, natural gas itself has a high calorific value and burns completely, with a thermal efficiency far higher than traditional fuels such as diesel and heavy oil, and the heat generated by combustion can be utilized to the greatest extent. The equipment is equipped with a purging fan and purging pipes. Before the equipment is shut down or under maintenance, the purging fan can send air into the regenerative combustion furnace. The airflow will thoroughly blow out any remaining combustible gases, dust and other impurities, preventing the accumulation of combustible gases into an explosive mixture. This fundamentally reduces the safety risks during equipment operation and maintenance, and ensures the safety of personnel and the production site. Attached Figure Description

[0013] The present invention will be further described below with reference to the accompanying drawings and embodiments: An RTO combustion aid device includes a base 12, on which a regenerative combustion furnace 1 is fixedly mounted. A combustion torch 2 is provided on the upper part of one side of the regenerative combustion furnace 1. A combustion unit 13 is provided on one side of the regenerative combustion furnace 1. The air inlet of the combustion unit 13 is fixedly connected to one end of a natural gas pipeline, and the other end of the natural gas pipeline is fixedly connected to a natural gas supply pipe. The air inlet of the combustion unit 13 is fixedly connected to the air outlet of a combustion aid fan 5 through an air supply pipe 501. The combustion unit 13 is connected to the combustion torch 2 through a pipe.

[0014] In this embodiment, air is supplied to the combustion unit 13 via the combustion fan 5 through the air supply pipe 501, and natural gas is supplied to the combustion unit 13 via the natural gas supply pipe. After the two are mixed in the combustion unit 13, the combustion unit 13 delivers natural gas to the combustion torch 2, and the combustion torch 2 ignites the natural gas injection flame, which is burned in the regenerative combustion furnace 1. The heat generated by the combustion of natural gas is used to heat the regenerative combustion furnace 1, providing a high-temperature environment for subsequent waste gas treatment. Natural gas combustion produces fewer emissions, without generating harmful substances such as dust, smoke, and sulfides, resulting in less environmental pollution. Natural gas combustion has a high calorific value and high thermal efficiency, allowing for effective utilization of the heat generated and reducing energy waste. The combustion flame is also more stable, ensuring complete combustion. The gas outlets at the upper and lower ends of one end of the regenerative combustion furnace 1 are respectively connected to the chimney 3 by gas outlet pipes 101.

[0015] During operation, the exhaust gas in the regenerative combustion furnace 1 is heated and undergoes an oxidation reaction in the combustion chamber. The high-temperature gas generated enters the exhaust pipe 101 through the upper and lower exhaust ports and is then discharged into the chimney 3.

[0016] The regenerative combustion furnace 1 is fixedly equipped with maintenance platforms 4 at its upper and lower parts, respectively. The upper maintenance platform 4 is connected to the second ladder 11, and the lower maintenance platform 4 is connected to the second ladder 11.

[0017] In accordance with ergonomics and safe operating procedures, maintenance platforms 4 are installed at the upper and lower parts of the regenerative combustion furnace 1 to provide workers with a safe and stable working space. Ladders provide workers with access to and from the maintenance platforms 4, facilitating workers to inspect, maintain and repair the upper and lower parts of the regenerative combustion furnace 1, and ensuring that workers can safely reach the parts that need maintenance.

[0018] A purge fan 9 is also provided on one side of the regenerative combustion furnace 1. The outlet of the purge fan 9 is connected to the inlet of the purge pipe 8, and the purge pipe 8 is fixedly connected to the lower part of the other side of the regenerative combustion furnace 1.

[0019] In this embodiment, after the purge fan 9 is started, air is sent to the lower part of the other side of the regenerative combustion furnace 1 through the purge pipe 8. The air flow blows out the residual combustible gas, dust and other impurities in the combustion furnace, which helps to keep the inside of the combustion furnace clean.

[0020] The regenerative combustion furnace 1 has inspection ports 6 at both ends of the upper part of one side for easy maintenance.

[0021] An air inlet is provided at the lower part of the other end of the regenerative combustion furnace 1. The exhaust gas enters the regenerative combustion furnace 1 through the air inlet, where it exchanges heat with the high-temperature gas generated by combustion. After being heated to a certain temperature, an oxidation reaction occurs in the combustion chamber, decomposing the organic pollutants in the exhaust gas into carbon dioxide and water.

[0022] The method of using this utility model is as follows: The combustion system is started, and the combustion fan 5 is turned on. The combustion fan 5 sends air into the combustion unit 13 through the air supply pipe 501. At the same time, the natural gas supply pipe valve is opened, and natural gas enters the combustion unit 13 through the natural gas pipeline. The air and natural gas are mixed in proportion in the combustion unit 13. The ignition device of the combustion unit 13 is started through the combustion torch 2. After the mixed gas is ignited, the flame enters the regenerative combustion furnace 1 to heat the inside of the combustion furnace until the temperature inside the furnace reaches the temperature required for the oxidation of waste gas (usually 750-850℃). When the exhaust gas supply system is turned on, the exhaust gas to be treated enters the furnace through the air inlet at the lower end of the other end of the regenerative combustion furnace 1. It exchanges heat fully with the high-temperature gas generated by combustion and is heated to the oxidation temperature. An oxidation reaction occurs in the combustion chamber, and organic pollutants are decomposed into carbon dioxide and water. The high-temperature purified gas generated by the oxidation reaction enters the exhaust pipe 101 through the air outlets at the upper and lower ends of one end of the combustion furnace and is finally discharged through the chimney 3. When purging the regenerative combustion furnace 1, shut off the exhaust gas supply and the combustion unit 13, stop the natural gas supply, keep the combustion fan 5 running for 5-10 minutes, and at the same time start the purging fan 9 to send air into the combustion furnace through the purging pipe 8 to thoroughly blow out the remaining combustible gas and impurities in the furnace until the furnace temperature drops to a safe range (usually below 100℃). Regular maintenance: Climb the ladder to the maintenance platform 4, open the maintenance port 6, inspect the heat storage body and combustion chamber wall inside the combustion furnace, and remove ash or impurities; check the combustion unit 13 and pipe joints for wear or leakage, and replace damaged parts in time; remove rust and reinforce the ladder and maintenance platform 4 to ensure safety performance.

[0023] The above-disclosed embodiments are merely specific examples of this utility model. However, this utility model is not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of this utility model.
